These poly transmission mounts will have less movement under braking and cornering and, moreover, will not transfer much noise into the cabin which will make the ride a bit easier. These are a bolt through design (10.9-grade hardware); Hardware has a nylon insert, to ensure it does not back out on its own. These mounts are great for spiritedly-driven BMW streetcars. Moreover, these mounts are great for Auto-x use as well! Do it right, do it once, do it Garagistic.
